I have read all the responses to manually uploading an add-on. For some reason the add-on I picked is not automatically coming over to my Dashboard to be used on my webpage. So, I am willing to try and manually upload it. However, each of the instructions are quite detailed about doing this until they reach the part about uploading to my site's /packages/ folder. How exactly do I do this. Webpage creation is brand new to me so I need some step by step directions to tell me where to go and what to click. I have it downloaded to my PC as a zip file. Just need to know what to do from here.
